改了一下设置，看看到底每天多少人，顺便估算一下日均IP与实际人数的比例。 http://www.hylt.net/vb/showthread.php?t=9120 管理成员曾经内部说过，海洋论坛注册达到1万人后，为了保证交流质量，将逐步走向封闭，可能采用邀请注册、注册审核、民主评分等机制。期望未来情况是人气中等、质量上乘。所谓人气中等，我理解是24小时在线成员100至500人。超过500人，信息量将大增，有价值信息的比重同时也会降低，大家每个人的信息筛选成本就会提高，逐步降低其中较高水平成员的参与热情。
Webalizer Quick Help http://www.mrunix.net/webalizer/webalizer_help.html 15. Why do my reports show more Sites than Visits? Visits are only triggered when a valid request is found for a page, as defined by your PageType setting (or a URL that ends with a slash, which is also considered a page type). Sites however, are counted regardless of the request type. It is very common to have more sites than visits, particularly if you host non-pagetype URLs on your site that are linked to from the outside. If you are not hosting URLs that are linked to from outside sites, then make sure your PageType setting is correct. The default is .htm, .html and .cgi extensions, unless you specify otherwise.
